Fee Schedule

There is a minimum charge of one hour for each party.


$360 per hour shared by parties. Prepayment may be required and other details may vary given the nature of such assignments. Please contact Chris directly for assistance.


There are no cancellation fees, no matter when the cancellation occurs.


While both parties and/or insurance carriers likely are ultimately responsible for payment of the bill, the attorneys are the guarantors of payment of the bill. It is not possible to screen each party’s credit; as such reliance is upon the attorneys rather than requiring pre-payment. If the mediation goes forward as scheduled, there is a minimum charge of one hour for each party. Pro se parties are required to pre-pay an amount that is the best forecast of their expected bill, but will be billed or refunded promptly following completion of mediation.
